Likely fix
Fix: iPhone storage is full
iPhone storage usually fills up because of photos, videos, apps, messages, offline downloads, and System Data.
Quick answer
Open iPhone Storage settings, review the biggest categories, offload unused apps, delete large videos, and enable optimized photo storage if you use iCloud Photos.
